Diamonds

A Diamond can be broken if shot. An impact can break or chip a diamond regaurdless of how perfect the stone is. A diamond cannot be scratched however except by another Diamond.

However, because of its value, you might not want to use a diamond for target practice. Instead, you could consider using a pea or a kernel of corn -- a diamond of either size would be quite valuable: up to tens of thousands of dollars if it were a 'perfect' stone.

Initials inside a shield are generally the maker's mark. From 1695 to 1720 it was more common to use the first two letters of the maker's name instead of the initials. Nowadays, three initials is the most popular method to identify the maker.

The "18K" part means the gold is 18-karat gold. The metal in the band is 75% gold and 25% a mix of other metals.

The 4 Cs of diamonds are cut, color, clarity, and carat weight. Cut refers to the diamond's proportions and how well it reflects light. Color ranges from colorless to yellow, with colorless diamonds being the most valuable. Clarity measures the presence of inclusions or blemishes within the diamond. Carat weight simply refers to the weight of the diamond.

The term "SI" indicates a clarity category, not a colour category.

For clarity, "SI" indicates slightly included, and is usually followed by a number, 1, 2, or 3. In this scale, fewer is better.

The best way to identify a diamond is to use a diamond tester. It is a handheld device which sends a thermal beam (heat) inside the stone and reads how fast the stone conducts the heat. Each mineral has a different heat conductive coefficient so this way you can tell a diamond from other stones.

However, a moissanite (a withe stone grown in the lab) has the same response as a diamond so a diamond tester may confirm the moissanite as a diamond.

Recently, a moissanite tester has been developed , so it can differentiate a diamond from a moissanite. Also a moissanite turns deep yellow when heated with a torch then turns back to white when cools down.

Also, it is possible that a trained eye can see a greenish color it the moissanite.

A diamond is much denser and harder than talc. Diamonds are made of carbon and are formed under high pressure, making them very hard, while talc is a soft mineral composed of hydrated magnesium silicate. In terms of size, a diamond is typically much smaller than a piece of talc due to their different compositions and structures.

Environmental impacts of diamond mining include land degradation, deforestation, and water pollution. Social impacts may include displacement of communities, human rights abuses, and conflict financing in diamond-producing regions. Economic impacts can vary; while diamond mining can bring economic benefits to a region, the revenues may not always benefit local communities or be sustainable in the long term.

A diamond's contents are primarily carbon atoms arranged in a crystal lattice structure. Trace elements may also be present, influencing the diamond's color.

The "14k" stamp on the inside of a diamond ring indicates that the ring is made of 14 karat gold. The "f" could possibly denote the manufacturer or designer of the ring, but it would be best to consult with a jeweler to get more specific information.

Yes, generally, this is true. Especially when one uses the word 'broken' to connote an accident.

Rarely, however, if a stone has a flaw or weak spot and is hit 'just right' so as to fracture the stone at the weak spot, then you could say that the stone was 'broken'. Generally, stones with this sort of visible flaw is not sold as jewelry by a reputable dealer and would certainly be documented with any certificate the accompanied a stone.

Diamonds are used to cut metals because they are one of the hardest materials on Earth. The carbon atoms in diamond form strong covalent bonds, making it exceptionally resistant to wear. This hardness allows diamonds to effectively cut through metals with precision and efficiency.

Cut and faceted gemstone diamonds reflect the light, which some call shiny.

Raw diamonds are dull rocks. Only 20% are sorted out for processing as gemstones and are cut, graded, and polished into valuable gems.

Eighty percent are industrial diamonds that are used to enhance precision tools.

Palladium is similar in appearance to white gold, but since it does not have nickel as one of its ingredients, palladium is hypoallergenic. Palladium is considered a lightweight metal, similar in weight to 14K gold. Palladium metal can coat a ring or the ring can be "950 palladium," 95% palladium and 5% ruthenium, with possibly other traces of metal.

No, a diamond cannot cut through metal. While diamonds are one of the hardest materials known, they are brittle and could fracture when used to cut through hard metals like steel. Diamond is more commonly used to cut and shape other materials like glass, ceramic, or other diamonds.

No, diamonds are harder than enamel. Diamonds rank as the hardest natural material known, scoring 10 on the Mohs Scale of Hardness, while enamel, the outer layer of teeth, ranges from 5 to 7 on the scale.

Show your diamond to a professional jeweler. They can usually tell you right away whether the diamond in an engagement ring is real or not.

Another way to tell is to breathe hot air onto the diamond to fog it up. If the diamond holds the fog for a few seconds, it's fake. Real diamonds disperse the fog immediately.

Professional testing is by thermal and electrical conductivity measurements, or by optical study of the crystals.

Most diamonds that are mined -- 75% -- are employed by industry, because diamonds are harder than any other known mineral.

Over time, because of the flaws in formation of these stones, they may begin to separate at the weakest points -- the flaws -- so that the implement becomes less sharp and able to perform as expected.

In diamond-tipped hand-tools, this process probably takes several lifetimes, automated machine-driven tools, less time.

A gem-quality diamond without any flaws -- an expensive diamond -- could be melted if you could heat it to 3820 degrees Kelvin or 3546.85 degrees Celsius or 6416.23 degrees Fahrenheit.

Diamond is harder than glass, meaning that it has a higher Mohs hardness scale rating. Consequently, when a glass is used to cut diamond, the glass will simply break or shatter due to the extreme hardness of the diamond. Diamond is the hardest natural material on Earth, while glass is relatively softer compared to diamond.

No, diamonds and graphite are not polymorphs of silicon. Diamonds are a polymorph of carbon, while graphite is also a polymorph of carbon. Silicon does not form diamonds or graphite as polymorphs.

"DBJ" is likely the initials of the person who crafted the piece. It is common for jewelers to use three initials to mark their work.

The number 925 is a bit unusual to see on gold jewelry. Numbers such as 916 or 917 (22-karat gold) and 999 (24-karat gold) are more common.

If the 925 is inside an oval, the ring is more likely to be sterling silver.

It all depends on the quality. A 1 carat A-quality Tanzanite can cost a couple hundred dollars where a AAAA-quality Tanzanite can cost thousands of dollars. The same holds true for diamonds.

A diamond cuts glass by being drug across the surface of the pane of glass according to the desired pattern. Once so scored, the glass technician will use a rubber mallet to tap one side or the other of the score, to separate the glass into the desired shapes and pieces.

A diamond tool is used to cut glass, because diamond is the hardest mineral known.
